Internationally, the political appetite for educational measurement capable of capturing a metric of value for money and effectiveness has momentum. While most would agree with the need to assess costs relevant to quality to help support better governmental policy decisions about public spending, poorly understood measurement comes with unintended…

Instructional time use is an intervention without equal. The measure of such has clear and important implications for special education practice and research. Although exhortations to maximize instruction and thereby student engagement exist throughout the literature, few studies discuss how special education teachers use their time, and none…

The utility of value-added estimates of teachers' effects on student test scores depends on whether they can distinguish between high- and low-productivity teachers and predict future teacher performance. This article studies the year-to-year variability in value-added measures for elementary and middle school mathematics teachers from five large…

A modified time sampling procedure that measured behavioral rate and duration was used to record stereotypic and on-task responding in 11 students (ages 11-17) with severe emotional and behavioral disturbances. For both types of behavior, response duration exhibited less variability than response rate, and noncorrespondence between the two…

Evidence is presented on the generalizability and convergent validity of performance assessments using data from six studies of student achievement that sampled a wide range of measurement facets and methods. Results at individual and school levels indicate that task-sampling variability is the major source of measurement error. (SLD)

Features of the design of the National Assessment of Educational Progress (NAEP) are discussed, with emphasis on the design of the 1992 assessment. Student sample designs for the NAEP and the Trial State Assessment are described, and the focused-balanced incomplete block spiraling method of item sampling is discussed. (SLD)

Raw scores on most standardized educational and psychological assessment instruments acquire meaning only when referenced to a set of norms. Test publishers should clearly describe their norming procedures, including the target population and the sample on which the norms are based. The primary purpose of this report is to illustrate some of the…

A discussion of family literacy projects focuses on alternatives to traditional methods of program evaluation. In the first chapter, the distinction between standardized and alternative assessments is clarified and the special evaluation needs of family literacy projects are highlighted. The remainder of the handbook is intended to help program…

The measurement dilemmas involved in assessing the national educational goals established by the President and governors at the 1989 education summit are discussed. The first and most important choice is what to assess and whether to align assessment to the vision of curriculum reform or to the curriculum that students are actually experiencing.…

In this paper, performance assessments are cast within a sampling framework. A performance assessment score is viewed as a sample of student performance drawn from a complex universe defined by a combination of all possible tasks, occasions, raters, and measurement methods. Using generalizability theory, the authors present evidence bearing on the…

A central problem for the user of domain-referenced tests in instruction is deciding who has passed and who has failed. Two procedures were presented and discussed. The first, employing classical test theory, was found to be more useful for larger domains and where the passing standard is 70 percent or less. The sampling procedure suggested by…
